METHOD OF SEWING.

SPECIFICATION forming part of Letters Patent No. 399,310, dated March 12, 1889.

Application filed May Z8, 188% Serial No. 275,297 (No model.)

To @ZZ whom it may concer/L.- i

lie it known that we, GEORGE A. XANDER, residing at lianihnrg, and JOHN G. XANDER, residing at Reading, hothV in the county ot' Berks and State ol Pennsylwmia, haveinvented certain new and useful flnprorenieiits in the Method of Stitching; and we do declare the following to he a i' ull, clear, and exact description oll the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accornpanying drawings, and to the letters and figures olf reierelnifeniarked thereon, which forni a part of' this specification.

The ohject ot' this invention lis to forni a lock-stitch adapted more partieularly to fasten together materials which it is necesary to eure only at points a greater or less distance apart. The principle of the stitch used is the saine as that inyolred in the well-known glove-hitch, and our intention consists in a new nianner oi t'orining it. A niachine hy means ot? which this inay he done therefore not shown or described; hut we merel y ind-icate the increments required to forni the stitch in a ln-eierred manner.

Figure l represents the well-known glovehitch" or watermans knot. Fig. 2 shows our separate lock-stitch he'fore tightening, clearly indieating the general principle of: its const ruct io n.

Fig. Iii shows the successive loops required in making the stitch hy the preferred niethod illustrated in different stages in Figs. i to ll, each oi these loops, as well as their different t hreads, heing in dieat ed hy eorreslionding letters and figures th roughout. represents an eye-pointed needle, and l a suitable forni of rotary hook with point l and cast0tf"7 R2. B, (l, and l) represent the tirst, second, and third loops in the order in which. they are foi-ined, while l and 2 are the first and second threads ot' the first loop, 2l and i oli the seeond, and 5 and (5 ot' thethird. vll and T rcpresent. hooks which are adapted to seize and more the loops, as indicated.

Fig. l reyn'esents the first loop formed and caught upon the point of the Vrotary hook in the usual manner, the material inoyed ahead, and the needle ready for its second descent. Thread l is in the rear.

Fig. 5 shows the tirst loop twisted by the rotation ot the hook R2, which may be of the usual shape to effect this. The needle is ready for its second ascent and the point R of the rotary hook is preparing to enter the second loop. Thread l is in front.

Fig. Gshows the position of the first and second loops reversed, the second, C, having heen passed through the tirst by the rotation of the hook R, while the first is preparing to escape from the cast-off R2, andthe hook Il is in position to catch it. Threads l and el are in front.

Fig. 7 shows the ii rst loop caught hy the hook U, which is in the act ot pulling it through the second loop. The latter is still on the point end of the rotary hook, and threads l and at. remain in front.

Fig. 8 shows the second loop twisted, hringing thread 3 in front. The first loop has been pulled through it and is still on the hook ll, thread l heinghent around thread if and its end about to escape from the material. Thread 2 is twisted around thread b. '.llmneedlehas descended andthe point R ol therotaryhook is about to take up the third loop.

Fig. 9 shows the first loop '(lestroyed,thread l being freed from the material and as an cxtension of thread 2 thrown forward. This is the natural position of thread 2, it haring' heen previously twisted or hent around thread of the second loop, whereas it now passes straightthrough said loop. The third loop is on the rotary hook and being drawn through the second, the latter hein held hy the castoil" R2.

Fig. l0 shows the second loop freed from the cast-oil. R2, the third loop well drawn through it, and its rear thread, 5, engaged hy a hook, T, a sudden movement of which is adapted to tighten up the second loop, the tensionof the niain thread. heing sufficient to prevent it ironi heing pulled down.

Fig. lllV shows the knot or stitch tightened up, the thread 2 passing through the second or central loop in one direction, while the threads 5 and t3 pass through it in the opposite direction, the second loop holding them snug against the under side oi the material. The hook T, the lnoyenientoi which has thus tightened the knot, keeps the thread 5 IOO stretched until a suitable knife or shears is brought into play and it is cut at a point, K, thus permitting the end thread, G, to be withdrawn and remain with the needle while the material is moved onward to the desired point for another stitch, leaving the one just made substantially asshown in Fig. 2, except that in the latter it is not shown as tightened up.

It will be seen that this method of stitching will form a veryV secure fastening in all cases where it is not necessary that a continuous line of stitching should be used. A succession of stitches may be thus made, each knotted and entirely Vindependent of the others, and any desired distance apart. The main feature of the glove-hitch is maintainednamely, the tendency to tighten the knot on pulling either end of the thread. The general method of using it, however, as herein set forth, and as shown in Fig.2, is substantially different from the usual method shown in Fig. l, and we do not confine our invention to the preferred method of forming it by machine, as particuhtrly described herein.

NVhat we claim as new, and desire to secure by Letters Patent, is as follows:

l. The method of forming separate lockstitches, consisting in passing athread through the material at three points, so as to form a central loop and pulling both ends of the thread through said loop, substantially as sot forth.

2'. The method of forming separate lockstitches, consisting` in passing a thread through the material from one side thereof in a series of three loops and pulling both ends of thread through the central loop, substantially as set forth.

3. The method of stitching herein set forth, which consists in forming two loops, reversing' their position, pulling the end of the thread which forms the first loop through the second, forming a third loop, passing it through the second, and tightening the knot.

4. The method herein set forth of forming a series of lock-stitches,which consists in forming two loops, reversing their posit-ion, pulling the end of the thread which forms the first loop through the second, forminga third,

loop, passing it through the second, tightening the knot, cutting the thread, and moving the material into position for the next stitch.

In testimony whereof we aiiix our signatures in presence of two witnesses.
